The Handwerkskammer Hannover intends to modernize parts of the equipment in the workshops by 2018 at the campus craft in Garbsen, Seeweg 4.
A double-lacquer drying unit for component K.
This project is supported and supported by the Federal Institute for Vocational Education and Training (BIBB) and the Investment and Support Bank of Lower Saxony (NBank).
The scope of supply is the supply and installation of 2x lacquer drying booths in the design as a double-lacquer drying unit with a connecting gate for the building parts [K] of the campus craft, incorporating the existing 2 filling stations of the Wolf WFW 20-90 type and WLE-S 180 in the course of an energetic modernization.
New Building Faculty of Mechanical Engineering in Garbsen, 2.BA - VE066 - Compressed Air, Ladder Air and Gases
University campus with a useful area of NF 22 250 m², 4 institute buildings of mechanical engineering with test halls, laboratories, workshops, technical buildings, lecture hall and mensage buildings, house for students and dean's office, including free-standing facilities. In accordance with VOB part C, the construction measure is published and distributed in approx. 50 units.
The VE066 includes the central compressed air generation with distribution in the buildings 8140-8143. Furthermore, there is a distributed compressed air supply in buildings 8130 and 8131. Compressed air generated for the charge air (user) is carried out from building 8140 to 8141 as well as the distribution network in 8141.
In Building 8150 there is the natural gas transfer station and a natural gas compressor. In buildings 8140 and 8141, cable networks for HD natural gas are planned. A pipeline network for LP natural gas is provided in 8143. In addition, distribution grids made of stainless steel are used in buildings 8140 and 8141 for technical gases such as hydrogen and nitrogen.
- compressed air pipes DN 15 - DN 125: approx. 5 500 m;
- Natural gas pipelines DN 15 - DN 150: approx. 500 m;
- Stainless steel pipelines DN 8 - DN 20: approx. 800 m;
- Ladder air ducts DN 80 - DN 125: approx. 400 m.
The state of Lower Saxony plans for the Hannover Medical School the new conversion and extension of Technischen- and medical gases, depending on their use as pharmaceuticals and Medizinproduktegestzt (AMG. MPG) and DIN EN ISO 7396th
Medical compressed air 5 bar: air for ventilation purposes in a quality according to the European Pharmacopoeia. Medical compressed air 8 bar: air for driving surgical tools in a quality according to the European Pharmacopoeia.
Laboratory compressed air: air to supply the laboratory building in a quality similar to that of medical compressed air in the pressure levels 5 and 8 bar. Technical compressed air: air for the operation of pneumatic control and measuring systems as well as for the laundry operation, trash compactors, sterilization and kitchen facilities.

Approximately 2500 m loop, approximately 1 500m building connecting cable. Establishment of new air compressors for medical air. Renewal of transfer stations for the technical compressed air approximately 34 stations. Exchange or disassembly of valves in technical air supply. Reorganization measures existing Notversorgungsnetz, partial replacement of pipes and decommissioning unused line sections.
Construction of a 2-circuit supply structure for the distribution of medical oxygen.
- Approximately 3 500 meters loop;
- Approximately 1 500 meters building connecting cable. Adjustments to the oxygen-cold gasification plants on buildings K16 and the building L.

Electric Industrial excavator.
Subject of the tender is the creation / acquisition of a measurement module software ( "VOK measuring module") for the on-site inspection (VOK) the inspection service of the Agricultural Association (LWK). The inspection service of the Chamber of Agriculture requires a new measurement software for the implementation of VOK under the EU agricultural subsidies (IACS). This software is used to 105 measuring units, consisting of rugged, weather-protected Windows tablet computers and even such GNSS receivers. After removal of the software maintenance services (troubleshooting and / or delivery of new program versions) are to be performed and further develop the software in cooperation with the client and adapt to the respective needs. For the process of program development before and after the loss of authority is based on a workload of 300 hours for a software and / or database developers the contractor from. These hours can be retrieved by the client as needed.
Description of the transport processes of conservative gas tracers in saturated and unsaturated clay materials (bentonite, claystone) as well as hydromechanical analysis of gas injection tests in claystone and bentonite considering capillarity / water saturation and dilatation-controlled gas flow (case 1).
Hydromechanical analysis of fault zones in clay rock with consideration of crack flow (case 2).
Coupled THM analysis of heating tests in the French underground laboratory Bure (case 3).
Analysis of hydromechanical mechanisms for the release of fluid inclusion through the extension of drill holes or the drilling of wells as well as the migration processes of the fluid inclusions taking into account a thermal gradient during heating (case 4).
Based on the existing implicit coupling concept of the fully THM-coupled finite element code OpenGeoSys (OGS) version (V5.7), the following services are provided:
1. Implementation of
a. gas pressure dependent permeability function and
b. deformation-dependent permeability function taking into account plasticity for bentonites
2. Investigation and implementation of the new numerical algorithm for the calculation of gas flow with the extremely high gas inlet pressure in the capillary pressure-saturation relationship
3. Implementation of the x-FEM algorithm to investigate hydraulic pressure induced gap
4. Verification of the fully coupled THM models in the context of benchmark calculation with spot heat registration
5. Verification of the possibility of transfer from the small-scale model (bore scale) to the large-scale model (1: 1 tunnel) in non-isotropic mudstone by recalculation of
a. TED and
b. HA experiments.
6. Review of the applicability of the THM algorithm to pore structure (sub-pore scale).
